Notes:
- The value of I
∆n
and its multiplication factor along with current waveform must be selected in a
manner enabling the meter to perform the measurement. The set of measurement parameters, which
is not supported by the meter, can not be entered - when one parameter is entered the remaining
parameters change their values to default values (see Technical Specifications: Table of forced
current values).
- Measurement of response time t
AI
is not available for short-time delay switches and for selective
switches and for direct current.
- U
B
and R
E
values are measured with test current 0,4I
∆n
without RCD tripping. If during this
measurement RCD is tripped, the following message
is displayed for a while and the next
measurement (if applicable) (I
A
or t
A
) will not be performed.
- Due to the nature of the measurement (increase of I
A
current in steps), measured
disconnection/response time t
AI
in this mode may include a positive error or as a result of RCD inertia,
the following symbol may be displayed:
. If the result is not within the acceptable range for a given
RCD, repeat the measurement in t
A
mode (section 2.6.2).
- Enter the result into memory (see section 3.2) or press,
ESC
, to return to displaying only voltage
value. The last measurement result is stored until
START
button is pressed again or the position of
rotary switch is changed.
